Shufaluff, first I will ask you to change your tone, otherwise I will have to report you to the moderator of this forum. If you have a psychological problem and cannot repress agressivity bouts, please seek medical advice.
As I said, it is nonsensical to advise a traveller to take the train between Jerusalem and Tel Aviv or the reverse, as the Jerusalem train station is extremely far from the center of town.
The sheruts leave from Harav Kook street in Jerusalem seven days a week. Others leave from near the central bus station, which is less practical for tourists who usually stay around the Old City.
On shabbat, some sheruts leave from Harav Kook street and others leave from the itnersection between Road 1 and Haneviim street, five minutes from Damascus Gate.
In Tel Aviv, the sheruts leave from behind the bus station, where you will also find sheruts covering the city of Tel Aviv and all its neighborhoods, including during shabbat. That's why it's more practical to take sheruts than wait for the Egged buses inside the central bus station,
